Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| npm-metadata | suspicious-initial-version | AI (npm-metadata): concat-map is a 13+ year old legitimate package by substack (James Halliday). Version 0.0.0 reflects early npm ecosystem conventions, not malicious intent. | ai | |
| provenance | no-provenance | AI (provenance): Package predates Sigstore provenance by many years; absence is expected and not a risk signal for this package. | ai | |
| provenance | publisher-changed | AI (provenance): Publisher change from substack to ljharb is a well-documented legitimate stewardship transfer; ljharb is a trusted, prolific npm maintainer with consistent metadata across this package. | ai | |
| maintainer-change | maintainer-added | AI (maintainer-change): ljharb and nopersonsmodules are known maintainers in ljharb's ecosystem; addition reflects legitimate transfer from substack, not a compromise. | ai | |
| publish-pattern | dormant-publish | AI (publish-pattern): Dormancy reflects original substack abandonment; ljharb resuming maintenance is the expected explanation given consistent repo/funding metadata. | ai |
